Ok, I doubt anybody cares. I think that thing is entirely historical,and we probably should never have done it in the first place. I wonderif we should just replace that field with a zero.

We've moved flag bits around in task->flags (and moved them tothread->flags) before, so that /proc/<pid>/stat field has not beenstable historically either. I can't imagine what could break - itwould have broken many times before too.
